Title: Optical disc device
Inventor: TAKEMURA YOSHIYA
IPC: G11B7/125
Filed: 1983-12-15
Abstract: PURPOSE:To use a semiconductor laser to improve the recording density by providing a means which changes the output wavelength of a light source, which irradiates a disc in accordance with the output signal of an address detecting circuit, between the inside circumferential part and the outside circumferential part of the disc. CONSTITUTION:The address of a track where signals should be recorded is designated from an external device. A controller 15 refers to the address signal of the track read by an address detecting circuit 14 to move an optical head part B' to the address of the designated track through a transporting system 12. A switching circuit 20 selects the first semiconductor laser driving circuit 21 in case of the inside circumferential part of the track and selects the second semiconductor laser driving circuit 23 in case of the outside circumferential part in accordance with the address signal for recording. That is, the semiconductor laser having a short wavelength and a low output is used for the inside circumferential part of the disc, and the semiconductor laser having a long wavelength and a high output is used in case of the outside circumferential part, thereby improving the recording density.

Title: Picture recording system
Inventor: SHIMOOOSAWA HIROYUKI
IPC: H04N1/23
Filed: 1983-12-15
Abstract: PURPOSE:To decrease the capacity of a recording power supply and to attain high speed recording without uneven feeding by reducing the maximum black picture element number recorded at once less than one line total picture element number and carrying the subscanning feeding of a recording paper sheet at a fixed speed. CONSTITUTION:The heat-sensing recorder records a picture in the unit of one page and the maximum black picture element number recorded per one line is selected to a half K of the total picture element number of one line. In this recorder, the power supply having a capacity supplying simultaneously a maximum K-set (for 1/2 lines's share) of heaters is used and the capacity of the recording power supply is halved to that of one line simultaneous drive. Since the subscanning feed of the recording paper is performed at a fixed speed, generation of uneven feeding such as a case with the variable subscanning is prevented almost completely. Furthermore, the subscanning feed speed of the recording paper is increased sufficiently without use of expensive high performance motor as a stepping motor 40 so as to attain high speed recording.

Filed: 1994-09-30
Abstract: PURPOSE: To detect a correct date data signal even in a bad environment by providing a date data signal generation means showing information per '8' bit with plural pulse lines of three or more and recording, detecting means. CONSTITUTION: An R/P changeover switch 4 is switched to the R side by operation of a control part 10 in a sound recording mode, and an input sound from a microphone 1 is amplified by a sound recording amplifier 2 to be recorded on a magnetic tape 6 through a magnetic head 5.

Title: Ultrasonic flaw detector
Inventor: SASAKI TSUKASA
IPC: G21C17/003
Filed: 1987-09-24
Abstract: PURPOSE:To obtain the title ultrasonic flaw detector which is operated by a remote controller and performs both normal flaw detection and accurate flaw detection by itself by varying the quantity of engagement between gears for transmitting the power of each driving part properly according to circumstances. CONSTITUTION:An operator of the detector judges which of the normal flaw detection and accurate flaw detection is performed at a stage of judgement 50 and operates the controller panel 51 of the ultrasonic flaw detecting device 5. When the normal flaw detection mode 52 is specified, the distance between respective driving part gear shafts of the ultrasonic flaw detector 5 increases, but the quantity of engagement between the gears decreases, thereby performing the fast flaw detection with low accuracy. When the accurate flaw detection mode 53 is specified, on the other hand, the distance between the gear shafts of the respective driving parts of the ultrasonic flaw detector 5 decreases and the quantity of engagement between the gears increases, thereby performing the slow flaw detection with high accuracy.

Title: Data transfer control system for extended storage
Inventor: ANAYAMA NAOTO
IPC: G06F12/00
Filed: 1990-09-07
Abstract: PURPOSE:To omit the redesign of hardware by sending a write request to an extended storage when the time set at an access time holding means passed. CONSTITUTION:A comparator 6 compares the value of a counter 4 with the value of a register 5. When the coincidence is obtained between both values after 5Tx, an extended storage write request transmitting part 7 sends a write address 109 and a transfer data write request 104 to the extended storage. Receiving the request 104, the extended storage sends an acceptable report to a system controller 1 as long as the transfer data are acceptable and in a non-working state of refreshing, etc. Thus a common data transfer control part is secured and the redesign of hardware is not required.
